A sample collection of what?
For this, see this:
some of my voice samples.
The style you submit isn't too important; we look to analyse the quality of your microphone's recording and whether your voice is suitable.
If you're interested, UEaW's voices use an Admiral-style reporting point of view; instead of having different voices for every ship and squadron, each faction has a single admiral voice who reports the status in a calm manner; as if you were the Admiral of the Fleet and your assistant is reporting the ongoing battle to you.
Unit selection, e.g. Nebulon B is 'Escort frigate selected'
Move order, e.g. Nebulon B is 'Frigate navigation order issued'
Attack order is 'Engagement order issued'
Damage report, e.g. shield generator down on a VSD is 'Destroyer reports loss of shield generator'.
